This isn't about legal dog-hunting. It's about illegal dog-hunting.
This doesn't sound like hunting at all. More like harassing wildlife.
I've hunted with dogs once (legally) in Mississippi. It wasn't what most people imagine, certainly not what I was expecting. We were hunting on an island. Shooters were spread out in a line near one end of the island. The dogs (beagles) were released on the other end.
The dogs weren't chasing the deer, but slowly walking toward the other end of the island yapping as they walked. To my knowledge none of the beagles or deer ever saw each other. But the deer were moving, slowly, instead of holing up in thick brush.
I saw probably a dozen doe, but I wanted a buck or nothing. The deer casually fed as they walked, often staying in one spot for several minutes. As the dogs got closer, they simply moved on at a walk.
This was done mid-day in a steady rain. We stand hunted morning and evening but using the dogs mid-day in the rain was an effective way to keep them moving. In many places the same technique is used with other hunters instead of dogs. But it is a lot safer to use dogs.
There are lots of ways to hunt that may not be technically illegal but aren't ethical. I saw one example years ago in Colorado. Ranchers would lay down sections of fence making it easy for the elk to cross from public land onto their ranches. This also funneled the elk into specific areas of the ranch. Later, the fencing was put back up making it a little harder for them to move back to public land. The fence won't stop the elk, but most any animal takes the easiest path.
I was told that it was legal. What got some in trouble was when they started having ranch hands riding the fence line 24/7 on ATV's during hunting season to discourage the elk from leaving the ranches.
